Abstract

The invention discloses an elbow sealing performance test device, which comprises a rack. A water tank is arranged on the rack; the water tank is internally provided with a lifting plate; a lifting driving mechanism is arranged between the rack and the lifting plate; an elbow clamping position is arranged on the lifting plate; the lifting plate is provided with an elbow clamp for fixing the elbowon the elbow clamping position; the lifting plate is also provided with a sealing device for sealing the two ports of the elbow; the lifting plate is also provided with an air inlet device communicated with one port of the elbow clamped by the elbow clamp; the water tank is also connected with a water injection device; the lifting plate rises, the elbow is fixed on the lifting plate through the elbow clamp, the sealing device seals the two ports of the elbow, and later, the lifting plate falls to enable the elbow to be immersed in water in the water tank, and then, the air inlet device provides air for one port of the elbow, whether bubbles appear in the water tank is observed, the sealing performance of the elbow is judged, the operation is convenient, the test result is accurate and reliable, and the sealing performance of the elbow can be tested effectively.

Description

technical field [0001] The invention relates to an elbow tightness test device. Background technique [0002] In the prior art, manual detection is mostly used when performing the elbow tightness test, and the operation is repeated, and the detection efficiency is low. Moreover, due to the complete reliance on manual operation, deviations are prone to occur during the operation, and the test results cannot be effectively guaranteed. , and requires a lot of manpower. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides an elbow airtightness test device which can effectively improve the efficiency of the elbow airtightness test and ensure the accuracy of the test results. [0004] The technical solution of the present invention is: a bend pipe tightness test device, including a frame, a water tank is arranged on the frame, a lifting plate is arranged in the water tank, and a lifting plate is arranged between the f...
